CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit under 35 U.S.C. § 119(a) of a Korean patent application Serial No. 10-2016-0148535 filed in the Korean Intellectual Property Office on Nov. 9, 2016, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to a method and a device for displaying a user interface (UI) related to user authentication.

BACKGROUND

With the recent development of digital technologies, various types of electronic devices such as mobile communication terminals, personal digital assistants (PDAs), electronic organizers, smart phones, tablet personal computers (PCs), or wearable devices have been widely used. Hardware parts and/or software parts of such electronic devices have continuously been improved in order to support and increase functions.

For example, the electronic device may tack a picture through a camera, provide a wayfinding service through a navigation function, and provide a payment service through an input of a password (or input of a secret pattern) or a fingerprint sensor. When the user is authenticated using a fingerprint sensor, the electronic device may keep higher security as compared to user authentication using a password input. Accordingly, electronic devices are developed to provide not only the payment service but also various services such as financial transactions using the fingerprint sensor.

The fingerprint sensor may be provided at a button (for example, a home button) of the electronic device, and the user may bring his/her finger into contact with the button of the electronic device in fingerprint recognition. In other implementations, the fingerprint sensor is located in a display area of the electronic device rather than the button of the electronic device. For example, when the fingerprint sensor is located at the part of the display area and a user interface (UI) is displayed in the display area, the user cannot know the location at which the fingerprint sensor is arranged and thus may have difficulty in using fingerprint recognition.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

FIGS. 2A to 2D illustrate a layer structure of an electronic device including a fingerprint sensor according to various embodiments of the present disclosure.

FIG. 2A illustrates a layer structure of an electronic device 200 including a fingerprint sensor 250.

Referring to FIG. 2A, a top direction may be a front direction of the electronic device 200 and a bottom direction may be a back direction of the electronic device 200, and respective elements may be included within a housing (not shown).

On a front surface of the housing, a cover window 210 may be formed. The cover window 210 may be formed with a transparent surface. The transparent surface is formed with a transparent material through which light penetrates and formed to protect a display 240 from external impact.

A touch sensor 220 and the display 240 may be formed below the cover window 210, and the cover window 210 and the display 240 (or the touch sensor 220) may adhere to each other by an optically clear adhesive (OCA) 230. Although FIG. 2A illustrates that the touch sensor 220 is located above the display 240, it is not limited thereto and may be implemented in various types such as an on-cell type, an in-cell type, and a layered type. For example, the in-cell type may be a type in which a fingerprint sensor is embedded in a display panel or a black matrix (BM) area, and the layered type may be a structure in which the fingerprint sensor is layered on or below the display panel.

The touch sensor 220 may detect a touch of an object (for example, a user's finger or a stylus) generated on the cover window 210.

Below the display 240 (or the touch sensor 220), the fingerprint sensor 250 may be located. When a user's finger is located on the cover window 210, the fingerprint sensor 250 may be formed to acquire user's fingerprint information. According to various embodiments, since the fingerprint sensor 250 is formed in an area on the rear surface of the display 240 or the touch sensor 220, the user may touch the display 240 or the touch sensor 220 with his/her finger in order to make his/her fingerprint recognized.

For example, the fingerprint sensor 250 may include an in/on-cover glass type corresponding to a structure in which the sensing unit or the electrode for sensing the fingerprint is arranged on the surface of the cover glass through printing or etching, an over-display type in which the sensing unit or the electrode is arranged on the display panel, an under-display type in which the sensing unit or the electrode is arranged below the display panel, and an in-display type in which the sensing unit or the electrode is arranged inside pixels of the display panel or in a BM area between pixels.

Further, the type of fingerprint sensor 250 is not limited by the following description. For example, the fingerprint sensor 250 may include an optical type for acquiring the fingerprint by capturing a fingerprint image on the surface of the finger through photosensitive diodes, a capacitive type for acquiring the fingerprint based on a principle that parts (ridges) of the fingerprint contacting the electrode are detected and parts (valleys) which do not contact the electrode are not detected, and an ultrasonic type for generating ultrasonic waves using piezo and acquiring the fingerprint through a path difference of ultrasonic waves reflected from the ridges and the valleys of the fingerprint.

Hereinafter, although the case in which the optical fingerprint sensor is arranged under the display 240 and the touch sensor 220 (under-display type) is representatively described, all the above-described various embodiments may be applied to the present disclosure.

FIG. 2B illustrates an example of a fingerprint sensor located on a display of an electronic device according to various embodiments of the present disclosure.

As illustrated in FIG. 2B, the touch sensor may be formed on the rear surface of the display 240, and thus may not be visually recognized by the user. In this case, at least one area of the cover window, the OCA, the touch sensor, and the display 240 may include a transparent or a translucent area through which a predetermined amount or more of light penetrates, and the touch sensor may be arranged on the rear surface of the corresponding transparent or translucent area to acquire a user's fingerprint image. According to an embodiment, in at least one area of the display 240, the electronic device 200 may form a hole between pixels to enable a predetermined amount or more of light to penetrate therethrough. According to an embodiment, on a fingerprint sensing area 251 of the display 240, a user interface associated with a fingerprint recognition function may be displayed.

According to various embodiments, the size and/or the location of the fingerprint sensing area 251 is not limited. For example, the electronic device 200 may include a larger fingerprint sensing area 250 c as illustrated in FIG. 2C. Further, according to another embodiment, the electronic device 200 may include two or more fingerprint sensors as illustrated in FIG. 2D, and fingerprint sensing areas 251 d and 252 d corresponding to the respective fingerprint sensors may be formed on the display 240.

As described above, the type, location, number, size, and density of the fingerprint sensors included in the electronic device 200 may vary, and the electronic device 200 may store and manage information related to the fingerprints. For example, the type of fingerprint sensor may be divided into an optical type, a capacitive type, and an ultrasonic type according to a sensing type and divided into a touch type and a sweep type according to an input type, and the electronic device 200 may store information on the type of fingerprint sensor included in the electronic device 200 among the listed types. The location of the fingerprint sensor may be defined as a coordinate value (for example, coordinate value on x and y axes of the display) or a mechanical location value (for example, front/rear/left/right/top/bottom), or a location value corresponding to a component (for example, a home key, a menu key, or a camera), the size of the fingerprint sensor may be defined by horizontal and vertical lengths, and the density (or dpi) may be defined as poor/fair/good/best.

According to various embodiments, the electronic device 200 may include at least one fingerprint sensor on the rear surface of the display 240. As described above, a display (display 240)-integrated fingerprint sensor may be supported by various sizes of screens and various sizes/densities of fingerprint sensors ranging from a small portable electronic device to a large TV. Further, the fingerprint sensor 250 may be located at various positions on the display 240 of the electronic device 200. In addition, the fingerprint sensor 250 may have various sensing types for acquiring the fingerprint. Accordingly, in order to execute the application using the fingerprint recognition function in various types of electronic device 200, a service should be provided at a position as accurately as possible on the screen through compatibility of the size of various screens and the type, position, size, and density of fingerprint sensor. In order to efficiently provide the user interface (UI)/user experience (UX) according to the related art considering only the size and the direction of the display 210, a method of storing and managing resources corresponding to the type, position, size, and density of the fingerprint sensor is required. Further, graphic processing for selecting a suitable image set from resources based on information on the type, position, size, and density of the fingerprint sensor included in the electronic device 200 and drawing the image set in an appropriate layout may be needed.

FIG. 4A is a flowchart illustrating an operation method of an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 4A, in operation 451, the electronic device 100 (for example, the object identification module 311) may identify content including at least one object to be displayed on the display 320. The content may refer to a user interface or a user experience displayed on the display 320. For example, the content may be a page (for example, an execution screen of an application) consisting of at least one of text, an image, and a video.

In operation 453, the electronic device 100 (for example, the object identification module 311) may determine whether the content is associated with acquisition of fingerprint information. The content refers to a user interface and may include at least one object (for example, UI component). For example, at least one object may include a uniform resource locator (URL), a button (or a key), and an input item and may be selected by the user. Further, the content may further include an object (for example, a non-selectable object) having no reaction in spite of a user's selection.

The electronic device 100 may perform operation 455 when the content is associated with the acquisition of the fingerprint information, and perform operation 457 when the content is not associated with the acquisition of the fingerprint information.

In operation 455, the electronic device 100 (for example, the display configuration module 313) may perform control to display at least one object in at least some areas in which the fingerprint sensor (for example, the fingerprint sensor 321) is formed. For example, the display configuration module 313 may configure the content to display the object that requires user authentication at the position where the fingerprint sensor 321 is located (or embedded). The display configuration module 313 may configure the display such that another object corresponding to at least one object is displayed at a second predetermined position (for example, the position where the fingerprint sensor 321 is located). The display 320 may display content configured by the display configuration module 313.

In operation 457, the electronic device 100 (for example, the display configuration module 313) may perform control to display at least one object at a predetermined position. For example, the predetermined position may be determined by the framework stored in the memory (for example, 150). The display configuration module 313 may configure the display such that at least one object is displayed at a first predetermined position (for example, the original position to display the object within the content). The display 320 may display at least one object at the predetermined position.

FIG. 4B is a flowchart illustrating an operation method of an electronic device according to various embodiments.

Referring to FIG. 4B, in operation 401, the electronic device 100 (for example, the display 320) may display content. The content may refer to a user interface or a user experience displayed on the display 320. For example, the content may be an execution screen of an application related to a text message, a call, a web, a game, and a payment.

In operation 403, the electronic device 100 (for example, the object identification module 311) may identify objects within the content. The object may refer to data such as a text, an image, or a video constituting the content. The object configures a user interface may be referred to as a UI component. For example, the object may include a URL, a button (or a key), and an input item and may be selected by the user. Further, the content may further include an object (for example, a non-selectable object) having no reaction in spite of a user's selection.

In operation 405, the electronic device 100 (for example, the object identification module 311) may determine whether an object for user authentication exists in the identified objects. For example, the object for the user authentication may refer to an object that performs the operation thereof after a service for identifying the user such as an account registration (for example, member joining) service, a login service, a payment service, or a financial service is performed. For example, when the user desires to post an article online, the electronic device 100 identifies user information such as a user ID and a password, and, only when the user information is correct (for example, the login is completed), the article can be posted. Alternatively, when the user purchases a product online, the user should input payment information (for example, an account number of a card number) required for paying for the product along with the user information of the user who purchases the product. The object for the user authentication may refer to an object that requires user information.

In operation 407, the electronic device 100 (for example, the display configuration module 313) may identify the location of the fingerprint sensor. The fingerprint sensor (for example, the fingerprint sensor 321) may include a fingerprint sensing unit configured to detect (or recognize) a fingerprint and arranged in some areas, a plurality areas, or an entire area corresponding to the display 320. In general, the fingerprint sensor may be provided at a home button of the electronic device 100, and the fingerprint sensor 321 may be arranged in a display area of the display 320. Even though the fingerprint sensor 321 is arranged in the display area of the display 320, the fingerprint sensor 321 may be arranged at a lower center of the display 320 in consideration that the fingerprint sensor 321 is provided at the home button. For example, the fingerprint sensor 321 may be arranged in some areas such as the top/bottom/left/right portion of the display 320, or a plurality of fingerprint sensors may be arranged in a plurality of areas, respectively, or in an entire area of the display 320. Hereinafter, although it is described that the fingerprint sensor is arranged at the lower center of the display 320, the location of the fingerprint sensor is not limited by the following description.

In operation 409, the electronic device 100 (for example, the display configuration module 313) may move the location of the object for the user authentication to the position of the fingerprint sensor 321. For example, the location of the fingerprint sensor 321 is the lower center of the display 320, and the object for the user authentication may be arranged at an upper right side of the display 320. The display configuration module 313 may move the object for the user authentication to the lower center from the upper right side.

The display configuration module 313 according to various embodiments may delete the original object for user authentication when the object for user authentication moves. Alternatively, the display configuration module 313 may maintain the original object for user authentication without deleting it when the object for user authentication moves.

The display configuration module 313 according to various embodiments may change attributes of the object for user authentication based on attribute information of the fingerprint sensor. For example, the attribute information of the fingerprint sensor may include at least one of a size, a position, a shape, and a density of the fingerprint sensor. The display configuration module 313 may change at least one of a size, a position, a shape, and a color of the object for user authentication based on the attribute information of the fingerprint sensor 321.

In operation 411, the electronic device 100 (for example, the display 320) may display the moved object. For example, the display 320 may display changed content in which the object for user authentication within the content is moved to the position of the fingerprint sensor by the display configuration module 313. The content displayed in operation 401 may be the original content, and the content displayed in operation 411 may be the changed content. That is, the changed content may be content in which the position of the object of the original content is moved.

According to various embodiments, the fingerprint sensor 321 may recognize the fingerprint based on a user input by the user for selecting the object for user authentication in the content displayed in operation 411. The user may make a user input (for example, a touch input) on the object for user authentication. The fingerprint sensor 321 may acquire the fingerprint when the user presses the displayed object. The authentication module 315 may determine whether the acquired fingerprint matches the fingerprint registered (or stored) in the memory 150. When the fingerprints match each other, the authentication module 315 may perform user authentication based on user information stored in the memory 150.

According to various embodiments, the memory 150 may store at least one piece of fingerprint information, at least one piece of user information, and at least one piece of payment information. The user information may include a user ID and a password according to each web address. For example, a user ID and a password of a web address “A” and a user ID and a password of a web address “B” may be stored in the memory 150 as the user information by the user input. The payment information may include at least one of an account number for each band, a depositor name, and a password. The payment information may include at least one of a card number for each card, an expiration date, and a password.

When the object for user authentication detected in operation 405 is associated with a login, the processor 310 may extract user information of the logged-in web address from the memory 150 and transmit the extracted user information to an external electronic device (for example, a POS device or a web server). According to various embodiments, the user may perform a login based on user information stored in the memory 150 through fingerprint recognition by a user input of pressing a login button along without directly inputting a user ID and a password required for the login. When the object for user authentication detected in operation 405 is associated with payment, the processor 310 may extract payment information of a product to be paid for from the memory 150 and transmit the extracted payment information to an external electronic device (for example, a POS device or a web server). According to various embodiments, the user may pay for the product based on payment information stored in the memory 150 through fingerprint recognition by a user input of pressing a payment button without directly inputting a card number, an expiration date, or a password required for the payment.

According to various embodiments, although it has been described that the original content is displayed (for example, operation 401) and then the changed content in which the object is moved is displayed (for example, operation 411), the changed content may be displayed by moving the object before the original content is displayed. That is, operation 401 can be omitted.

FIGS. 5A and 5B illustrate examples of displaying a user interface according to various embodiments of the present disclosure.

FIG. 5A illustrates an example of changing and displaying a user interface associated with login.

Referring to FIG. 5A, the electronic device 100 (for example, the controller 180) may display a page 510 associated with a social network service. The page 510 may be a screen of a user interface associated with the social network service. The user may post his/her own article by selecting a particular object (for example, a comment button 511) within the page 510. In order to post the article, a login process for inputting a user ID and password may be necessary. In general, when the comment button 511 is selected on the page 510, the controller 180 may display a login page 520.

The login page 520 may include a user name (or ID) input item 521, a password input item 523, and a login button 525. The user may place the cursor on the user name input item 521 to input the user name and place the cursor on the password input item 523 to input the password, and, when the user name and the password are completely input, may select the login button 525. When the user selects the user name input item 521, the controller 180 may place the cursor and provide a keypad. When the user selects the password input item 523, the controller 180 may place the cursor and provide a keypad. That is, the user needs many selections and inputs in order to input user information (for example, the user name and the password).

When an object (for example, the comment button 511) for user authentication is included within the page 510 based on resource information of the page 510, the electronic device 100 (for example, the controller 180) according to various embodiments may display a page 530 in which the comment button 511 is moved to the position of the fingerprint sensor. Hereinafter, for convenience of description, the page 510 may be referred to as an original page 510, and the page 530 may be referred to as a changed page 530. The changed page 530 may be similar to the original page 510 with the only difference being position of the object for the user authentication. The controller 180 may detect a user input for selecting the comment button 531 within the changed page 530, perform fingerprint authentication based on the user input, and, when the fingerprint authentication is successful, perform a function corresponding to the comment button 531.

For example, the controller 180 may acquire the fingerprint based on the user input and determine whether the acquired fingerprint matches the registered fingerprint (for example, fingerprint recognition). When the acquired fingerprint matches the registered fingerprint, the controller 180 may extract user information required for login from the memory 150 and transmit the extracted user information to a web server associated with the social network service. The web server may receive the user information, and, when the received user information matches user information stored in the web server, allow the login. Accordingly, the user may log in to the social network service based on the transmitted user information without directly inputting the user ID and the password required for login. When the login is completed, the controller 180 may receive a page to write article from the web server and display the page.

In the related art, when the user selects the comment button 511 on the original page 510, the electronic device may provide a login page 520, and, only when user information input on the login page 520 is correct, provide the page to write the article. According to an embodiment of the present disclosure, the page to write the article may be directly displayed from the original page 510 or the changed page 530 through fingerprint recognition without displaying the login page 520.

FIG. 5B illustrates an example of changing and displaying a user interface associated with payment.

Referring to FIG. 5B, the electronic device 100 (for example, the controller 180) may display a page 550 associated with product purchase. The page 550 may be a screen of a user interface related to a product purchase page including product information 551 and a payment button 553. Further, the controller 180 may display a location 555 of the fingerprint sensor within the page 550. The user may purchase the product by selecting the payment button 553 within the page 550. In order to purchase the product, a login process or a payment process may be necessary. In general, when the payment button 553 is selected on the page 550, the controller 180 may display a login page (for example, the login page 520) or a payment page. When the payment button 553 is selected in the login state, a payment page for inputting a card number, an expiration date, and a password may be displayed.

When an object (for example, the payment button 553) for user authentication is included within the page 550 based on resource information of the page 550, the electronic device 100 (for example, the controller 180) according to various embodiments may display a page 560 or a page 570 on which the payment button 553 is moved to the position of the fingerprint sensor. Hereinafter, for convenience of description, the page 550 may be referred to as a first page 550, the page 560 may be referred to as a second page 560, and the page 570 may be referred to as a third page 570. The second page 560 and the third page 570 may be similar to the first page 550 with only difference in the location of the object for the user authentication. The second page 560 may include product information 561 and a payment button 563 which is the same as the payment button 553 on the first page 550 with only difference in the location thereof. The controller 180 may change attributes of the object for user authentication based on attribute information of the fingerprint sensor. The third page 570 may include product information 571 and a payment button, the size of which is changed from the payment button 553 on the first page 550 to be similar to attributes of the fingerprint sensor. That is, the payment button 573 on the third page 570 may be changed to have the size similar to the size of the fingerprint sensor and to be smaller than the payment button 553 on the first page 550.

According to an embodiment, the fingerprint sensor 135 corresponds to an optical fingerprint sensor and may be arranged in a structure of being layered with the display 131. The optical fingerprint sensor corresponds to a light emitting unit and may use a light source of the display 131. The light source from the display 131 may be reflected from the user's finger and penetrate the display 131 so as to enter a receiving unit of the optical fingerprint sensor. The controller 180 may change the light source from the display 131 to have a predetermined color (for example, green or white) in order to improve a recognition rate of the fingerprint image acquired by the fingerprint sensor 135. Accordingly, the controller 180 may change the color of the payment button 573 on the third page 570 into the predetermined color and display the changed payment button 573. Alternatively, the controller 180 may change the color of at least some areas of the payment button 573 into the predetermined color in response to a user input (for example, a touch input on the payment button 573) and display the changed payment button 573.

The controller 180 may detect a user input for selecting the payment button on the second page 560 or the third page 570, perform fingerprint authentication based on the user input, and, when the fingerprint authentication is successful, perform a function corresponding to the payment button. For example, the controller 180 may acquire the fingerprint based on the user input and determine whether the acquired fingerprint matches the registered fingerprint (for example, fingerprint recognition). When the acquired fingerprint matches the registered fingerprint, the controller 180 may extract payment information required for payment from the memory 150 and transmit the extracted payment information to a payment server. The payment server may receive the payment information, and, when the received payment information is effective, allow the payment. Accordingly, the user may purchase the product based on the transmitted payment information without directly inputting a card number, an expiration date, and a password required for the payment. When the payment is approved, the controller 180 may receive a payment completion page from a web server associated with product purchase and display the payment completion page.

In the related art, when the user selects the payment button 553 on the first page 550, the electronic device may provide a login page or a payment page, perform user authentication (for example, fingerprint authentication or login), and, only when the input payment information within the payment page is correct, provide a payment completion page. According to an embodiment of the present disclosure, a payment function may be performed along with the user authentication directly on the second page 560 or the third page 570 without displaying a separate user authentication (fingerprint authentication or login) screen (or page).

FIGS. 6A to 6E illustrate examples of configuring a user interface according to various embodiments of the present disclosure.

FIG. 6A illustrates an example of changing a location of an object for user authentication.

Referring to FIG. 6A, when an object 611 for user authentication is included within an original page 610, the electronic device 100 (for example, the controller 180) may move the object 611 of the user authentication to a position 613 corresponding to (for example, a position where a fingerprint sensor is arranged or installed) a fingerprint sensor (for example, the fingerprint sensor 135) and display the object 611. The controller 180 may configure a page 615 on which the original object 611 for the user authentication is deleted and an object 617 for user authentication is moved to the position of the fingerprint sensor. That is, as the controller 180 overlays the object 617 for the user authentication on the position of the fingerprint sensor, the object 617 for the user authentication may be overlaid on other objects arranged at the position of the fingerprint sensor.

FIG. 6B illustrates an example of changing a position of an area including the object for user authentication.

Referring to FIG. 6B, the electronic device 100 (for example, the controller 180) may analyze that an original page 620 includes an area A 621 (or a layer A), an area B 622, and an area C 623. The controller 180 may analyze the original page 620 by parsing a code configuring the original page 620. The controller 180 may identify that an object 624 for user authentication is included in the area B 622 on the original page 620 and a fingerprint sensor 626 is arranged in the area C 623 on the original page 620. The controller 180 may switch the area B 622 including the object 624 for the user authentication and the area C 623 in which the fingerprint sensor 626 is arranged. For example, the controller 180 may move the area B 622 including the object 624 for the user authentication to the position where the fingerprint sensor 626 is arranged, and move the area C623 in which the fingerprint sensor 626 is arranged to the original area B 622. That is, the controller 180 may configure a page 625 on which the area B 627 is moved to the area in which the fingerprint sensor is arranged and the position of the object 628 for user authentication included in the area B 627 is moved to the position in which the fingerprint sensor is arranged. The controller 180 may reconfigure objects included in the area B 627 and move the position of the object 628 for user authentication to the position at which the fingerprint sensor is arranged.

FIG. 6C illustrates an example of reducing an area within a page and changing a position of an object for user authentication.

Referring to FIG. 6C, the electronic device 100 (for example, the controller 180) may analyze that an original page 630 includes an area A 631 (or a layer A), an area B 632, and an area C 634. The controller 180 may determine that an object 633 for user authentication is included in the area B 632 of the original page 630. The controller 180 may reduce a size of an area constituting the original page 630. For example, the controller 180 may configure a page 635 on which the position of the object 633 for the user authentication is moved to the position at which the fingerprint sensor is arranged and the sizes of the area A 636, the area B 637, and the area C 638 are reduced. A background color or a style of a margin area 639 may be determined based on a background color or a style of the area A 636, the area B 637, or the area C 638. Accordingly, the margin area 639 may be displayed through the display 131 such that the user does not sense a difference.

FIG. 6D illustrates an example of preparing an area of a position at which the fingerprint sensor is arranged and changing a location of an object for user authentication.

Referring to FIG. 6D, the electronic device 100 (for example, the controller 180) may prepare an area 643 of a position 644 at which the fingerprint sensor is arranged on an original page 640. The controller 180 may determine whether an object 641 for user authentication is included within the original page 640. When the object 641 for the user authentication is included within the original page 640, the controller 180 may move the object 641 for the user authentication to the position 644 at which the prepared fingerprint sensor is arranged. For example, the controller 180 may configure a page 645 including an area 646 on which the position of the object 647 for user authentication is moved to the position at which the fingerprint sensor is arranged.

FIG. 6E illustrates an example of selecting proper resources from multiple resources and changing a location of an object for user authentication.

Referring to FIG. 6E, the electronic device 100 (for example, the controller 180) may analyze that an original page 650 includes an area A 651, an area B 652, an area C 654, and an area D 655. Further, the controller 180 may identify that an object 653 for user authentication is included near the area B 652 and a fingerprint sensor 656 is arranged within the area D 655. The controller 180 may reconfigure some areas of the original page 650 based on the position at which the fingerprint sensor 656 is arranged and screen resource information configuring the original page 650 stored on the framework. For example, the controller 180 may move the area B 652 close to the object 653 for user authentication to the position at which the fingerprint sensor is arranged and move the area C 654 and the area D 655 upward. Further, the controller 180 may reconfigure the area B 652 to move the object 653 for user authentication to the position at which the fingerprint sensor is arranged.

The controller 180 may configure a page 660 on which the object 667 for user authentication is moved to the position at which the fingerprint sensor is arranged and the area B 652 is reconfigured as an area B 664 and an area B′ 665. Through comparison of the changed page 660 with the original page 650, it may be noted that the positions of the area C 662 and the area D 663 except for the area A 661 are moved and the area B 652 is reconfigured as the area B 664 and the area B′ 665.

FIG. 7 is a flowchart illustrating a method of performing user authentication by an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 7, in operation 701, the electronic device 100 (for example, the controller 180) may select an object for user authentication. When a user input for selecting (or touching) the object for user authentication is detected, the controller 180 may determine that the object for user authentication is selected. The object for user authentication may include an object associated with an account registration service, a login service, a payment service, or a financial service.

In operation 703, the electronic device 100 (for example, the controller 180) may determine whether fingerprint authentication has been previously performed. The controller 180 may determine whether fingerprint authentication has been performed at least once before the object is selected. The fingerprint authentication may correspond to acquiring the fingerprint from the user and determining whether the acquired fingerprint matches the registered fingerprint. For example, the user may unlock the electronic device 100 through the fingerprint authentication and execute a desired function (or application). In this case, the controller 180 may determine that the fingerprint authentication according to the unlocking of the electronic device 100 has been performed.

The controller 180 may perform operation 705 when the fingerprint authentication has been previously performed, and perform operation 711 when the fingerprint authentication has not been previously performed.

In operation 705, the electronic device 100 (for example, the controller 180) may determine whether an authentication elapse time is equal to or shorter than a reference value. The controller 180 according to various embodiments may maintain an authentication state for a predetermined time after the fingerprint authentication. The controller 180 may guide an indicator related to the authentication state. For example, the controller 180 may display the authentication state in an indicator area, change and display a color related to the authentication state, or display a timer for an authentication time. The indicator area may be an area for displaying various pieces of information (for example, signal strength, amount of battery, and time) related to the electronic device 100.

For example, when the user makes a request for user authentication again within a reference value (for example, 5 minutes or 10 minutes) after the fingerprint authentication, the controller 180 may perform the user authentication based on the previously authenticated fingerprint information without separate fingerprint authentication. However, when the user makes a request for user authentication after a reference value (for example, 1 hour) passes after the user authentication, the controller 180 may make a request for re-authentication.

The controller 180 may perform operation 707 when the authentication elapse time is equal to or shorter than the reference value, and perform operation 711 when the authentication elapse time is longer than the reference value.

In operation 707, the electronic device 100 (for example, the controller 180) may perform user authentication based on previous fingerprint information. For example, the electronic device 100 may recognize the fingerprint based on the fingerprint used when the electronic device 100 was unlocked. Alternatively, the electronic device 100 may recognize the fingerprint based on the fingerprint previously acquired when the user selects the object for the user authentication.

In operation 709, the electronic device 100 (for example, the controller 180) may display a page according to user authentication. For example, the controller 180 may perform a function corresponding to the object for user authentication displayed in operation 701. When the object for user authentication is a login button, the controller 180 may transmit user information required for the login to a web server to perform the login and display a page provided after the login is completed. When the object for user authentication is a payment button, the controller 180 may transmit payment information required for payment to a server to perform the payment and display a page provided after the payment is completed.

In operation 711, the electronic device 100 (for example, the controller 180) may perform a process for user authentication. The process for user authentication may correspond to moving the object for user authentication displayed in operation 701 to the position at which the fingerprint sensor is arranged and displaying the moved object, and performing fingerprint authentication based on a user input for selecting the displayed object for user authentication. That is, the process for user authentication may include operations 407 to 411 of FIG. 4B. Further, the process for user authentication may correspond to providing a page (for example, a login page or a payment page) associated with user authentication, receiving information required for user authentication within the page, and performing the user authentication based on the received information.

FIG. 8 illustrates examples of maintaining user authentication according to various embodiments of the present disclosure.

Referring to FIG. 8, the electronic device 100 (for example, the controller 180) may perform fingerprint recognition through a fingerprint sensor in a lock state 810 of the electronic device 100. When the fingerprint acquired through fingerprint sensor matches the registered fingerprint, the controller 180 may unlock the electronic device 100 and display an unlocked screen 820. The unlocked screen 820 may be a home screen (or a background screen) of the electronic device 100 or an execution screen of an application. Here, the unlocked screen 820 may be the home screen. The controller 180 may detect a user input for selecting an icon 815 of an application on the home screen. The controller 180 may execute the selected application and display an execution screen 830 of the application.

The execution screen 830 of the application may be a login page on which a user name and a password are input using a user name (or ID) input item 831 and a password input item 833. The controller 180 may determine whether the object for user authentication is included in the execution screen 830 of the application. The executions screen 830 of the application corresponds to the login page, and thus includes the object for user authentication. The controller 180 may determine whether the fingerprint authentication has been previously performed, and, when the fingerprint authentication has been performed, determine whether the authentication elapse time is equal to or shorter than a reference value. When the authentication elapse time is equal to or shorter than the reference value, the controller 180 may display a page 840 provided after the login is completed. That is, the controller 180 may display the page 840 provided after the login is completed without passing through a user authentication process in which the object for user authentication is moved to and displayed at the position of the fingerprint sensor and the fingerprint recognition is performed through the display object.

FIG. 9 is a flowchart illustrating a method of performing fingerprint authentication by an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 9, in operation 901, the electronic device 100 (for example, the controller 180) may display a user interface. The user interface may be a screen provided through the display 131 of the electronic device 100. For example, the user interface may be a home screen of the electronic device 100 or an execution screen of an application.

In operation 903, the electronic device 100 (for example, the controller 180) may detect a user input. The user input may be a touch input that touches the display 131. For example, when the user interface displayed in operation 901 includes a keypad, the user input may be an input that touches the keypad. Alternatively, when the user interface displayed in operation 901 is the home screen, the user input may be an input that selects an icon of the application within the home screen or touches an area in which no icon is arranged. At this time, the user input may be a continuous touch input.

In operation 905, the electronic device 100 (for example, the controller 180) may acquire the fingerprint based on the user input. For example, the fingerprint sensor may be arranged in at least one of a partial area, a plurality of areas, and an entire area of the display 131. When the user input is detected at the position at which the fingerprint sensor is arranged, the controller 180 may detect the fingerprint. That is, when the user input is detected at the position at which the fingerprint sensor is not arranged, the controller 180 may execute a function corresponding to the user input. For example, when the user input is an input for selecting a key on the keypad, the controller 180 may input a character corresponding to the selected key into an input field in response to the user input for selecting the key at the position at which the fingerprint sensor is not arranged. Further, when the user input is detected at the position at which the fingerprint sensor is arranged, the controller 180 may acquire the fingerprint when the character corresponding to the selected key is input into the input field and simultaneously the key is pressed. According to various embodiments, the fingerprint acquired in operation 905 may be the part (for example, 30% or 50%) or the entirety of the fingerprint that the user should input.

In operation 907, the electronic device 100 (for example, the controller 180) may store the acquired fingerprint in a buffer. The controller 180 according to various embodiments may store all acquired fingerprints in the buffer. Alternatively, the controller 180 may selectively store only fingerprints available for fingerprint recognition in the buffer among all the acquired fingerprints. The buffer according to various embodiments may store a fingerprint (or fingerprint data) for a predetermined time in a first in first out (FIFO) scheme. For example, when the fingerprint is stored in the buffer, the stored fingerprint may be stored only for a predetermined time (for example, 3 minutes, 5 minutes, or 10 minutes), and when the predetermined time passes, the stored fingerprint may be deleted.

In operation 909, the electronic device 100 (for example, the controller 180) may select an object for user authentication. The controller 180 may provide a user interface different from that in operation 901 according to the user input in operation 903. The controller 180 may detect a user input that touches the object for user authentication within the user interface provided by the user input.

In operation 911, the electronic device 100 (for example, the controller 180) may generate a fingerprint image based on the stored fingerprint. The controller 180 may generate a fingerprint image based on one or more fingerprints stored in the buffer. For example, the fingerprints stored in the buffer may be fingerprint of a user's different fingers such as a thumb, an index finger, and a middle finger. In this case, the controller 180 may generate one fingerprint image for each similar or same finger. For example, the controller 180 may generate each of fingerprint images for the thumb and the index finger based on the fingerprints stored in the buffer.

The controller 180 according to various embodiments may selectively perform operation 911. That is, after performing operation 909, the controller 180 may perform operation 913 without performing operation 911. Alternatively, the controller 180 may perform operations 909 and 911, and then operation 913. Operation 911 can be omitted.

In operation 913, the electronic device 100 (for example, the controller 180) may determine whether the fingerprint matches the registered fingerprint. The controller 180 may determine whether the fingerprint stored in the buffer matches the registered fingerprint at a predetermined ratio or more. The fingerprint stored in the buffer may not have sufficient size to determine 100% matching accuracy. In this case, the controller 180 may determine whether only the part of the fingerprint matches the registered fingerprint. The predetermined ratio may be determined according to a security level of the object for user authentication.

For example, when the object for user authentication is for the login service and thus has a “low” security level, the predetermined ratio may be 50%. In this case, when the fingerprint stored in the buffer matches the registered fingerprint at a rate lower than 50%, the controller 180 may perform operation 917 for security. Alternatively, when the object for user authentication is for the payment service and thus has an “intermediate” security level, the predetermined ratio may be 70%. In this case, when the fingerprint stored in the buffer matches the registered fingerprint at a rate lower than 70%, the controller 180 may perform operation 917 for security. When the object for user authentication is for the financial service and thus has a “high” security level, the predetermined ratio may be 100%. In this case, when the fingerprint stored in the buffer matches the registered fingerprint at a rate lower than 100%, the controller 180 may perform operation 917 for security.

According to various embodiments, since the fingerprint is deleted when a predetermined time passes after the fingerprint is stored, no fingerprint data may be stored in the buffer at a time point at which a fingerprint image is generated. For example, when operation 909 is performed in an hour after operations 903 to 907 are performed, no fingerprint data may be stored in the buffer. In this case, the controller 180 may determine that re-authentication is necessary and perform operation 917.

The controller 180 may perform operation 915 when the fingerprint matches the registered fingerprint, and perform operation 917 when the fingerprint does not match the registered fingerprint.

In operation 915, the electronic device 100 (for example, the controller 180) may display a page according to user authentication. For example, the controller 180 may perform a function corresponding to the object for user authentication. When the object for user authentication is a login button, the controller 180 may transmit user information required for the login to a web server to perform the login and display a page provided after the login is completed. When the object for user authentication is a payment button, the controller 180 may transmit payment information required for payment to a server to perform the payment and display a page provided after the payment is completed.

In operation 917, the electronic device 100 (for example, the controller 180) may perform a process for user authentication. The process for user authentication may correspond to moving the object for user authentication to the position at which the fingerprint sensor is arranged and displaying the moved object, and performing fingerprint authentication based on a user input for selecting the displayed object for user authentication. That is, the process for user authentication may include operations 407 to 411 of FIG. 4. Alternatively, when the object for user authentication has been already moved to and displayed at the position at which the fingerprint sensor is arranged, the controller 180 may perform fingerprint authentication based on the user input for selecting the object for user authentication.

The controller 180 according to various embodiments may perform fingerprint authentication using the acquired fingerprint based on the user input while the continuous user input is detected, and thus identify in advance that the authenticated user is using the electronic device. In this case, the controller 180 may perform user authentication based on the previously identified fingerprint information without a separate fingerprint authentication process in the situation in which the fingerprint authentication is required.

The controller 180 according to various embodiments may identify that the authenticated user is using the electronic device through the acquired fingerprint based on the user input, and, when the continuous user input is detected, determine that the authenticated user is continuously using the electronic device and maintain the user-authenticated state. Further, when user authentication is required after the user input is stopped for a predetermined time, the controller 180 may determine that the user using the electronic device is not the authenticated user and make a request for re-authentication.

FIG. 10 illustrates examples of using a fingerprint image on different pages according to various embodiments of the present disclosure.

Referring to FIG. 10, the electronic device 100 (for example, the controller 180) may detect a user input on a keypad 1011 within an execution screen 1010 of a message application. When the user input is detected at a position 1013 at which a fingerprint sensor is arranged, the controller 180 may acquire the fingerprint based on the detected user input. The controller 180 may perform fingerprint authentication through the acquired fingerprint, and when the acquired fingerprint matches the registered fingerprint, determine that the user authentication is completed. The controller 180 may display an execution screen 1030 of a browser application based on a user input for selecting a URL within the execution screen 1020 of the message application.

The controller 180 may determine whether an object for user authentication is included within the execution screen 1030 of the browser application. The execution screen 1030 of the browser application may be a login page on which a user name and a password are input and may include the object for user authentication. The controller 180 may determine whether fingerprint authentication has been previously performed in response to a user input 1031 that selects an item for inputting the user name. For example, the controller 180 may determine whether fingerprint authentication has been previously performed in the message application displayed before the execution screen 1030 of the browser application. When the fingerprint authentication is completed by the user input detected on the keypad 1011 within the execution screen 1010 of the message application, the controller 180 may perform user authentication within the execution screen 1030 of the browser application based on fingerprint information used for the completed fingerprint authentication. When the user authentication is completed, the controller 180 may provide a page 1040 provided after the login is completed.

Only when the request for user authentication is made within the execution screen 1030 of the browser application within a reference value (or a reference time) after the fingerprint authentication is completed within the execution screen 1010 of the message application, the controller 180 according to various embodiments may perform the user authentication within the execution screen 1030 of the browser application based on the fingerprint information used for the completed fingerprint authentication. When the request for user authentication is made within the execution screen 1030 of the browser application after a reference value after the fingerprint authentication is completed within the execution screen 1010 of the message application, the controller 180 may make a request for re-authentication.

FIG. 11 is a flowchart illustrating a method of applying an authentication result by an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 11, in operation 1101, the electronic device 100 (for example, the controller 180) may perform user authentication on a first window. The first window may be one window on multiple windows. Alternatively, the first window may refer to one display on multiple displays. The user authentication may refer to user authentication through fingerprint recognition. The user authentication may include the fingerprint authentication described in FIGS. 4A and 4B, 7, and 9.

In operation 1103, the electronic device 100 (for example, the controller 180) may make a request for user authentication on a second window. The second window may refer to another window other than the first window on which the user authentication is completed. The request for user authentication may correspond to selecting an object for user authentication such as a member joining service, a login service, a payment service, or a financial service on the second window.

In operation 1105, the electronic device 100 (for example, the controller 180) may perform user authentication on the second window based on the authentication information of the first window. The controller 180 may perform user authentication on the second window based on the fingerprint information acquired from the first window. When the user authentication is completed, the controller 180 may display a page provided after the user authentication within the second window is completed.

FIG. 12 illustrates examples of applying an authentication result on multiple windows according to various embodiments of the present disclosure.

Referring to FIG. 12, the electronic device 100 (for example, the controller 180) may provide a multi-window 1210 including a first window 1211 that displays a page associated with a social network service and a second window 1213 that displays a page associated with a login page. When user authentication within the second window 1213 is needed, the controller 180 may display a floating button 1215 at a position at which a fingerprint sensor is arranged. The controller 180 may detect a user input on the floating button 1221 and acquire a fingerprint by the detected user input. A second multi-window 1220 illustrates an example of acquiring a fingerprint through a floating button 1221. The controller 180 may perform fingerprint authentication by comparing the acquired fingerprint with the registered fingerprint. After the fingerprint authentication is completed on the second window, the controller 180 may maintain the displaying of the floating button 1231. On a third multi-window 1230, the controller 180 may detect a user input for moving the floating button 1231 within the second window to the first window. The controller 180 may determine that the request for user authentication is made on the second window by the user input for moving the floating button 1231 within the second window to the first window. When the floating button 1233 moves to the first window, the controller 180 may use fingerprint information, which has been used for fingerprint authentication on the second window, for the user authentication. The controller 180 may perform user authentication within the first window based on the fingerprint information on the second window.

FIGS. 13A and 13B illustrate examples of applying an authentication result on a two-sided display according to various embodiments of the present disclosure.

FIG. 13A illustrates an example of arranging a fingerprint sensor on a display.

Referring to FIG. 13A, the electronic device 100 may include a first display 1310 on the front surface of the electronic device 100 and a second display 1320 on the rear surface of the electronic device 100. On the first display 1310 and the second display 1320, fingerprint sensors having different fingerprint recognition rates may be arranged. As the fingerprint recognition rate is higher, fingerprint accuracy may be higher. Alternatively, the fingerprint sensor may be embedded into only one of the first display 1310 and the second display 1320. For example, a first fingerprint sensor 1311 may be arranged on the first display 1310 and a second fingerprint sensor 1321 may be arranged on the second display 1320. For example, the first fingerprint sensor 1311 may have a fingerprint recognition rate lower than that of the second fingerprint sensor 1321. Alternatively, the second fingerprint sensor 1321 may have a fingerprint recognition rate lower than that of the first fingerprint sensor 1311.

The controller 180 of the electronic device 100 according to various embodiments may determine the fingerprint sensor to be used for fingerprint recognition based on a security level of user authentication. For example, the controller 180 may use the fingerprint sensor having the high fingerprint recognition rate for user authentication such as payment and financial transactions, and use the fingerprint sensor having the low fingerprint recognition rate for user authentication such as membership registration or login.

FIG. 13B illustrates an example of using fingerprint sensors for a both-sided display.

Referring to FIG. 13B, a fingerprint sensor may be embedded into a first display 1350 located on the front surface of the electronic device 100, and a fingerprint sensor may not be embedded into a second display 1360 located on the rear surface of the electronic device 100. In this case, the controller 180 of the electronic device 100 may perform a control to use a result of fingerprint authentication performed on the first display 1350 for the second display 1360. That is, when an object that requires user authentication is selected on the second display 1360 within a predetermined time, the controller 180 may use an authentication result on the first display 1350. For example, when the user identifies product information 1351 on the first display 1350 and selects a payment button 1353, the controller 180 may perform fingerprint authentication based on the fingerprint acquired when the payment button 1353 is selected. When the fingerprint authentication is completed, the controller 180 may keep the fingerprint information acquired on the first display 1350 to be used on the second display 1360.

The controller 180 according to various embodiments may display the payment button 1353 at a position at which the fingerprint sensor is arranged on the first display 1350 including the fingerprint sensor and display the payment button 1363 at an original position on the second display 1360 including no fingerprint sensor with respect to the same page including the same objects (for example, the product information and the payment button). When the user identifies the product information 1361 on the second display 1360 and selects the payment button 1363, the controller 180 may indicate fingerprint authentication through the first display 1350 for fast user authentication. The controller 180 may display a notification message (for example, a popup message, an icon, or an arrow) to enable the user to switch the second display 160 to the first display 1350. When the second display 1360 switches to the first display 1350 for fast user authentication, the controller 180 may detect a user input on the payment button 1353 on the first display 1350 and perform fingerprint authentication. After the fingerprint authentication is completed, the user may switch back the first display 1350 to the second display 1360.
